Description

Sorbitan, Didodecanoate CAS NO 28905-44-4 is a non-ionic surfactant and emulsifier derived from sorbitol and lauric acid. This versatile chemical intermediate is valued for its excellent lipophilic properties and stability, making it a key component in formulations requiring controlled hydrophobicity. It is primarily sought by manufacturers in the personal care, cosmetics, and specialty chemical industries for its role as a solubilizer, dispersant, and viscosity modifier.

Application

• Primary emulsifier and co-emulsifier in cosmetic creams, lotions, and ointments.
• Solubilizer for fragrances, essential oils, and active ingredients in personal care products.
• Dispersing agent and viscosity modifier in industrial lubricants and metalworking fluids.
• Key intermediate in the synthesis of more complex surfactants and specialty esters.
• Additive in textile processing to improve fiber lubrication and softness.
• Component in agricultural adjuvant formulations to enhance pesticide and herbicide efficacy.
• Used in food-grade applications as an emulsifier (where compliant with relevant regulations).
• Plasticizer and processing aid in select polymer and resin systems.
